devel-warn compatibility issues in tests when building against mercurial 4.6
Created originally on Bitbucket by C (Matthew Gabeler-Lee)
There are new instances of devel-warn that are breaking test-clone and test-pull-after-strip when building tip (58c61489f722) against mercurial 4.6:
devel-warn: changectx.__init__ is getting more limited, see context.changectxdeprecwarn() for details
(compatibility will be dropped after Mercurial-4.6, update your code.) at: /usr/lib/python2.7/dist-packages/mercurial/localrepo.py:849 (__contains__)
Suppressing these warnings is easy. Fixing the compatibility issue looks like it is more work.
